Ferris Wheel A Ferris wheel with a diameter of 165 feet was built in St. Louis in 1986. It is called Colossus. The top of the wheel stands 174 feet above the ground. Use the diagram in Figure 14 as a model of Colossus.

a. Find *h* if

b. Find *h* 11

c. Find *h* if

To determine

If

above the ground h when

**Given information:**

**Calculation:**

Also, given that the diameter of Colossus is 165 feet, which means radius is 82.5 feet. Since the top of the wheel stands 174 feet above the ground, the distance from the ground to the bottom of the wheel is 9 feet (the distance to the top minus the diameter of the wheel, ie. 174-165=9).

Now, we will use the cosine ratio to write an equation that contains h as follows;

**b.**

To determine

If

above the ground h when

**c.**

To determine

If

above the ground h when
